WARNING: Tool bits may be hot and
gloves should be worn when changing
or removing them to avoid personal
injury.
WARNING:
• Be aware of the location of pipework
and wiring.
• Apply only a gentle pressure to
the tool (approx. 20 kg). Excessive
force does not speed up drilling but
decreases tool performance and may
shorten tool life.
• Always hold the tool firmly with both
hands and ensure a secure stance.
Always operate the tool with the side
handle properly assembled.
NOTE: Operating temperature is (-7 to +40˚ C (19˚
to 104˚ F). Using the tool outside of this temperature
range will decrease the life of the tool.

hammerdrilling position.
3. Set the electronic speed and impact control
dial (g).
4. Fit and adjust the side handle (c).
5. Mark the spot where the hole is to be drilled.

the tool. Drill until the core penetrates into the
concrete approx. 1 cm.
7. Stop the tool and remove the centerdrill. Place
the core bit back into the hole and continue
drilling.
8. When drilling through a structure thicker than
the depth of the core bit, break away the round
cylinder of concrete or core inside the bit at
regular intervals.
To avoid unwanted breaking away of concrete
around the hole, first drill a hole the diameter of
the centerdrill completely through the structure.
Then drill the cored hole halfway from each side.

and before unplugging.
